Technical specifications
Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 505 m³/h |
| Speed | 1950 rpm |
| Power | 83 W |
| Frequency | 50/60 Hz |
| Voltage | 230V AC VAC |
| Motor frame | The fan is supplied with a galvanised steel casing without a flange. The mounting position is arbitrary due to the installation-dependent enclosure class IP54. The motor is vibration-dampened on both sides for reduced vibration transmission to the mounting structure. |
| Casing | sheet, galvanized |
| Impeller | The fan wheel is a 120 mm forward-curved, dual-intake impeller. It is made of galvanized sheet metal. The rotor surface is thick-film passivated for corrosion protection. The rotor is open with no condensate drain. |
| Bearing type | hybrid bearing |
| IP class | IP54 |
| Motor protection | Electronic motor protection |
| Motor code | M3G055-BI |
| Rotation direction | clockwise, looking at the rotor |
| Motor type | The motor is an EC motor, type M3G055-BI, for single-phase operation at 230 V AC and 50/60 Hz. It features electronic motor protection with functions such as soft start, current limiting, overvoltage detection, and thermal overload protection for the electronics and motor. The motor is vibration-damped on both sides and has insulation class B. Control input 0–10 V DC or PWM enables variable speed control. |
